HEAT nnriino'ron.

Application filed March 11,1926. a Serial NO. 93,993.

For a detailed description of the present form of my invention, reference may be had to the following specification and to the accompanying drawing forming a part thereof, wherein Figs. 1 and 2 show in end view the re versed positions of the deflector;

Fig. 3 is a plan of the deflector in position;

Fig. A shows it detached and Fig. 5 shows one of the operating cams.

My invention relates to a car seat having a heating radiator secured beneath it with a reversible heat-shield or deflector, the same being an improvement on a device of that general nature shown in the patent of F. WV. Butt, No. 948,309, dated February 8, 1910.

Referring to the drawings, A and B are two rock-shafts extending longitudinally beneath the seat above the heater E and journalled in any suitable manner at their ends.

of the shafts A and B is a cam G split to embrace the shaft and be clamped thereto by a bolt. Each cam has a curved end that bears on a flat spring H extending transversely across'the top of the deflector from opposite sides, as shown in Fig. 4, and fastened thereto at one end but free at the opposite end. The cams G, G, being fast on the respective shafts, are each revolved thereby slightly more than 180 degrees as those shafts are rotatedby the reversal of the seat backs. Thus the cams occupy alternately the positions shown in Figs. 1 and 2 and act alternately by pressure on their respective springs H, H to elevate the rear edge and depress the front edge of deflector F, as shown in the same figures. The front cam in each case bears strongly on the resilient free end of its spring H, while the rearcam is out of action but forms a stop for the deflector. By this simple means the deflector F is positively reversed and locked 5i and in either position is held by spring pressure from shifting or rattling.

The purpose of the deflector is to guide the heat rising from the heater so as to protect the seat and its occupant and to divert 50 it diagonally upward and then backward towards the seat in the rear. This function of the deflector is aided by the angular extensions of the deflector, one or the other of said extensions extending downwardly from the deflector in front of the heater and the other extension being spaced upwardly from the heater and lying in an approximately horizontal position.

What I claim as new and desire to secure by Letters Patent is: v

1. A heat deflector for a car seat mounted above the heater and below the seat and provided with a reversing connection to the back of the seat including a spring secured 7 to the deflector, and means movable into engagement with said spring to yieldingly hold the deflector in its reversed position.

2. A heat deflector for a car seat mounted above the heater and below the seat and 3 provided with a reversing connection to the back of the seat including rock-shafts, cams on said shafts. and operating links between said shafts and the back of the seat.

A heat deflector for a car seat mounted above the heater and below the seat and provided with a reversing connection to the back of the seat including rock-shafts, cams on said shafts bearing on springs secured to the back of the deflector and operating links for said shafts worked by the back of thesea-t.

4. A heat deflector for a car seat pivotally and centrally mounted above the heater and. below the seat with operating cams therefor, one on each side of thefpivotal axis, and operating connections between each of said cams and the back of the seat.

v5. A heat deflector for a car seat pivotally and centrally mounted above the heater and below the seat, with two parallel rock-shafts operated by the back of the seat in revers-. ing, two cams, one on each of the respective rock-shafts and free-ended springs on the said deflector on which the said cams respectively bear. g I g 6. A heat deflector for a car seat comprising a flat body the longitudinal edges of which are provided with downwardly and outwardly inclined extensions, means by which said deflector may be movably mounted above a heater and below the seat and maintained: in an inclined position, a reversing spring. connected; to the deflector, and means movable into engagement with said spring to yieldingly hold the deflector in its reversed positions, so that in either of the inclined positions of said body one of said extensions will closely overhang the heater and the other extension will be elevated to a horizontal position to allow free escape of any heatwhich may accumulate beneath said body.

Signed at Albany, county of Albany, State of New Yorlgithis 8th day of March, 1926.
